Interface not showing up until tab out?

I did post this to the UI section but it pertains heavily to the code I use so I am not sure which is the correct place, please let me know.

So I have been struggling with getting my inventory system to show up properly. I spawn them into the correct places I DO use the transform.SetParent() function and panels are still invisible until I either disable and enable the GO or click another window and then the unity editor.

Here is the code that spawns all the slots [code=CSharp]public void BuildInv(string InventoryString){ //List slots = new List (); InventoryRawString = InventoryString;

     float slotwidth = this.gameObject.GetComponent<RectTransform>().sizeDelta.x / xRows;
     float slotheight = this.gameObject.GetComponent<RectTransform>().sizeDelta.y / yRows;
     for (int countery = 1; countery <= yRows; countery++) {
             for (int counterx = 1; counterx <= xRows; counterx++) {
                 GameObject slot = (GameObject) Instantiate(SlotPrefab);
                 slot.transform.SetParent(transform, false);
                 LayoutRebuilder.MarkLayoutForRebuild (slot.transform as RectTransform);
                 slot.GetComponent<RectTransform>().anchoredPosition = new Vector2 (0,0);
              
             }
     }
  
     transform.parent.gameObject.SetActive(false);
     transform.parent.gameObject.SetActive(true);
     //LoadInventory();
 }[/code]

Here you can see the interface buttons hidden?? http://i.imgur.com/cQnzqLk.png

And when I select another program and the click the unity editor http://i.imgur.com/ZnSeMOD.png
